Wiener kernel analysis of a noise-evoked otoacoustic emission.
In one specimen of the frog species, Rana esculenta, the following were measured: (1) a spontaneous otoacoustic emission; (2) a click-evoked otoacoustic emissions; and (3) a noise evoked otoacoustic emission. From the noise evoked emission response, a first- and a second-order Wiener kernel and the first six polynomial correlation functions were calculated by cross-correlating the stimulus and response signals. A peak near 850 Hz was visible in the spontaneous otoacoustic emission, the click-evoked emission and the noise-evoked emission. The higher order cross-correlation functions did not display any indication of the emission response. Apparently, that the noise stimulus linearizes the evoked emission from the frog's ear.
